Luami Engine

👑 Lumai Engine

Make games in C#. Your way.

Lumai Engine is a game engine and editor made by Grand Interactive. It works a lot like Godot, but everything is written in pure C# on .NET 10. You build scenes from nodes, write C# scripts, press Play, and your game runs right inside the editor. When it's ready, one click builds it for Windows or the web.

✨ Features

🧱 Nodes and scenes
Everything in a scene is a node. Nodes form a tree: move a parent and its children follow. Drag nodes to re-parent them, press Ctrl+D to duplicate, and use Ctrl+Z / Ctrl+Y to undo and redo.

🎮 2D and 3D

• 2D: sprites, your own PNG images, colliders, and a ready-made platformer controller (run, jump, coyote time).
• 3D: meshes, lights, shadows, cameras, and a character controller with a follow camera.

▶️ Play inside the editor
Press Play (F5) and your game runs right in the viewport. Press Stop and everything goes back the way it was.

💻 C# scripts with a built-in code editor
Add a script to any node and Lumai writes a starter for you. The Script tab checks your code as you type, underlines mistakes in red, and suggests code with Ctrl+Space. Public fields show up in the Inspector, so you can tweak values without touching code.

🔊 Sound in one line
Audio.Play("laser.wav") plays a sound effect and Audio.PlayMusic(...) plays looping music. Both support pitch, volume and pan.

🕹️ Game UI kit
Main menus, pause menus, results screens, buttons, sliders, toggles, progress bars and banners. They work with mouse and keyboard, and you can recolor them all with one line.

📦 One-click builds

• Windows: one self-contained .exe. Players don't need to install anything.
• Web: runs in any modern browser (WebAssembly + WebGL2), plus a .zip ready to upload to itch.io.

🏠 Project Hub
Create and open projects from one place, and start from templates that already run: 3D Starter, Solar System, 2D Platformer, or an empty 2D or 3D scene. A Learn page explains every part of the engine in plain words.

⚡ Built for speed
Nodes live in flat arrays and built-in components are structs, so the engine's game loop allocates 0 bytes per frame. That means no hitches from the garbage collector.

🚀 Made with Lumai: Star Crown

Star Crown is a pixel-art space shooter built entirely in Lumai Engine. It has menus, waves of enemies, power-ups, sound and music. It's included as an example of what you can make.

🖥️ Requirements

• Windows 10 or 11 (64-bit)
• A graphics card with OpenGL 3.3
• Nothing else to install. The engine is a single .exe.
